Video Server with Tertiary Storage

This paper discusses the design and implementation of a video server which uses tertiary device as a source of media archiving. In order to handle the tertiary device in the framework of disk-based stream service model, an effective disk caching mechanism is devised together with stream scheduling and admission control mechanisms. The proposed system has been implemented on a general-purpose operating system and its design principles are validated the with real experiment results. The results guide us how streaming servers with tertiary storage should be configured in real environments.
